Like Apple Pay, Android Pay still has not cracked the hardest barrier of all big U.S. retailers.

Almost no major U.S. retail brands appear in the Where to Use Android Pay page at the app’s website. Such behemoths as Walmart, Amazon, Kroger, Home Depot, Lowes, CVS, Burger King, Safeway, and Target are conspicuously absent from the list. The same sorry situation is repeated at Apple Pay, where almost all the big names in U.S. retail are conspicuously absent.

Despite the risks, the U.S. credit industry is capable of generating a lot of cash, which can lead to high levels of float. Float is Warren Buffett’s term for a constant stream of revenue or stockpile of cash that a company can tap or borrow against at any time.

The Superchargers don’t make money—they cost money—and the disturbing thing is that they could make money.

In a recent Bloomberg interview, Ready makes Venmo and Braintree sound like a sort of Google for financial transactions. That is an open sourced platform through which a wide variety of transactions are made. The difference is that Braintree’s transactions are financial.

Square has also tried to launch its own payments apps called Square Cash and SnapCash. Square Cash is a payments app similar to Venmo and Apple Pay; SnapCash is a variation of Square Cash reengineered to work over the popular social network Snapchat. In other words, it’s Square’s answer to Venmo. One difference is that it can work with merchants that use Square.
